Default
The switch generates a key for each SSH2 session.
Usage Guidelines
Secure Shell 2 (SSH2) is a feature of ExtremeWare that allows you to encrypt session data between a
network administrator using SSH2 client software and the switch, or to send encrypted data from the
switch to an SSH2 client on a remote system.
SSH2 functionality is not present in the base ExtremeWare XOS software image, but is in an additional,
installable module. Before you can access any SSH2 commands, you must install the module. Without
the module, the commands do not appear on the command line. To install the module, see the
instructions in Appendix A, "Software Upgrade and Boot Options".
After you have installed the SSH2 module, you must generate a host key and enable SSH2. To generate
an SSH2 host key, use the
command.
An authentication key must be generated before the switch can accept incoming SSH2 sessions. This can
be done automatically by the switch, or you can enter a previously generated key.
If you elect to have the key generated, the key generation process takes approximately ten minutes, and
cannot be canceled after it has started. Once the key has been generated, you should save your
configuration to preserve the key.
To use a key that has been previously created, use the
enter the pregenerated key. You can use the
generated key, and then copy and paste it after the prompt from the

NOTE
Keys generated by ExtremeWare XOS cannot be used on switches running ExtremeWare images, and
keys generated by ExtremeWare cannot be used on switches running ExtremeWare XOS images.
The key generation process generates the SSH2 private host key. The SSH2 public host key is derived
from the private host key, and is automatically transmitted to the SSH2 client at the beginning of an
SSH2 session.
